+static void ahci_check_irq(AHCIState *s)MSI support would be nice to have.Alrighty, I added MSI support. But I only have a single vector in use atm as nvec> 0 doesn't get written to the PCI config space so the code trips on that later on.
For multiple vectors MSI-X is the best choice as it fixes a few design issues MSI has when it comes to multiple vectors. I think linux never ever uses MSI with multiple vectors anyway.
